Hydrothermal Synthesis and Crystal Structure of a One-dimensional Copper（Ⅱ） Complex

A metal-organic coordination polymer [Cu(cbba)2(bix)]n(Hcbba = 2-(4'-chlorine-benzoyl)-benzoic acid,bix = 1,4-bis(imidazol-1-ylmethyl)-benzene) 1 has been hydrothermally synthesized and characterized by elemental analysis,IR,TG,UV and single-crystal X-ray diffraction.Blue crystals crystallize in the monoclinic system,space group C2/c with a = 26.127(3),b = 10.6143(14),c = 14.5676(19) ,β = 111.289(2),V = 3764.3(8) 3,C42H30Cl2CuN4O6,Mr = 821.14,Dc = 1.449 g/cm3,F(000) = 1684,Z = 4,μ(MoKα) = 0.777 mm 1,the final R = 0.0528 and wR = 0.1200 for 2241 observed reflections(I > 2(I)).The structure of 1 exhibits a one-dimensional chain-like structure.
